That's fine but there are drivers (USB, etc) doing
struct something { int field1; char dma_buffer[SMALLER_THAN_CACHE_LINE]; int field2; }; struct something *dev = kmalloc(sizeof *dev, GFP_KERNEL); Do they have to change to How about allocating struct something using pci_pool? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
